C.A.T. oil AG is one of the leading independent oil and gas field service contractors in Russia and Kazakhstan and is listed on the Frankfurt Stock Exchange (SDAX). C.A.T. oil provides a range of high quality services, which enable oil and gas producers to extend lifecycle of their fields or bring yet unexploited oil and gas reserves to production.
Since its foundation in 1991 in Celle, Germany, C.A.T. oil has built up a leading hy- draulic fracturing service, a very effective method of well stimulation by cracking rock formations with pressurized fluids, in Russia and Kazakhstan. Following its IPO in

In total, the Company has already invested more than EUR 450 million in growth and diversification since its IPO in
2006.
Following the successful set up of high class drilling in 2011-12, C.A.T. oil introduced its new segment reporting in 2013 clustering its activities in "Well Services" (fracturing, cementing and completion operations) and "Drilling, Sidetracking and IPM (Integrated Project Management)".
